Abstract :
Vortex shedding occurs on a Maglev train when there is sufficiently high-speed wind blowing perpendicularly on it. The vortex shedding will cause the suspension to fluctuate and, in the event of strong wind, may even cause the suspension to vibrate to failure. In this paper, a simplified model that only considers the vertical motion of the train is used to illustrate the effects of the vortex shedding. Under a given suspension control system, it is shown through simulation that winds of different speeds cause different degrees of performance degradation of the control system.
